The ultimate guide for X and Y in safety capacitors
The X capacitor provides a clean AC signal to the circuit and is therefore affected by all AC line changes, which can be dangerous if the capacitor''s voltage or power threshold is exceeded. Due to the special design of the X capacitor, its failure mode is short circuit, which triggers the circuit breaker or the fuse to open under overstress.
